| 摘 要： | 本文利用MHD波与日冕大气耦合的磁流体动力学方程组,计算得到冕洞内的日冕大气的温度T、密度N和流速V的分布.根据这些量的分布特点,认为日球基本参数T、N和V的冕洞周变化,可以用冕洞磁场的非径向因子a值,随黑子活动的下降而变小来解释.

| Abstract: | The distributions of. temperature T, density N and velocity V are given using the equations coupling the MHD waves with the coronal atmosphere. It is found that coronal-hole cycle variations of some basic heliospheric parameters, such as V, T and N can be explained by the decrease of the nonradial factor a of the magnetic field in the coronal hole as solar activity is decreased. |
